Can soft triangle area be resected to round it out & can kenalog/5FU create a supratip break? (Photos)

Had revision rhinoplasty 2 years ago, w/rib cartilage to form a defined tip. Excellent results; however, the nostrils look bad due to soft triangle areas having excess skin or cartilage. Can this be resected to round it out? I dislike how they angle downard toward the columella. The tissue to resect in the left soft triangle feels like cartilage from my tip, and right side may be skin or cartilage. ALSO, can kenalog or 5FU create a supratip break? (If I tape it, I get a supratip break for a day)
